Final answer:
To determine if suspicious sounds are phonemes, you can identify if they correspond to specific phonemes in a language.
Step-by-step explanation:
In order to determine if suspicious sounds are phonemes, you need to understand what phonemes are. Phonemes are the smallest units of sound in a language that can change the meaning of a word. They are represented by letters or groups of letters. For example, in the word 'cat', the /k/, /æ/, and /t/ sounds are all phonemes. When listening to suspicious sounds, you can try to identify if they correspond to specific phonemes in a language. If they do, then they are likely to be phonemes.
